The controversy concerning the validity and reliability of generalized anxiety disorder (GAD) appears to be particularly relevant
in the elderly, since physical symptoms associated with GAD can readily be considered as the consequences of normal aging.
This study aims to analyze the structure invariance of a questionnaire assessing the DSM-IV diagnostic criteria across samples
of older adults and college students. Ninety-seven adults aged 65 or over and 130 college students completed the Worry and
Anxiety Questionnaire (WAQ). The results revealed that factorial invariance could be assumed and, in addition, that scores
for severity of GAD symptoms were higher in younger subjects than in older ones. The results support the applicability of
DSM-IV criteria for GAD in elderly people, as the factorial structure of the WAQ was the same for this age group as for younger
adults. A higher degree of GAD severity was found in the younger sample.

The breakdown of European society is changing rapidly, particularly in the field of religion. Culture is of vital importance to the presence of religion in all nations. Religions also have exerted a certain degree of political power, thus influencing the economy and other related spheres of life.The different religions in Europe exhibit a variety of attitudes towards religious pluralism. The religious differences between Western and Eastern Europe depend mainly on issues of national identity related to religious adherence.This essay provides an overview of religion and politics, or Church and state, in Europe. It will conclude with some reflections about possible future developments within religious traditions in Europe. New religious communities and religious organisations are reaching different parts of Europe, sometimes very far from their place of origin. Christianity (Catholicism, Orthodoxy, and Protestantism) is the most widespread religion in contemporary Europe. Catholic religion is well diffused in Europe, but there are substantial differences in belief, behaviour and practice within different Catholic communities. There are various branches of Orthodoxy in Europe, such as the distinct autocephalous churches. In general Orthodox religion is closely aligned with national culture. Islam is also present in Western countries, and its impact is evident. 相似文献

ABSTRACT— Aging is associated with preserved enhancement of emotional memory, as well as with age-related reductions in memory for negative stimuli, but the neural networks underlying such alterations are not clear. We used a subsequent-memory paradigm to identify brain activity predicting enhanced emotional memory in young and older adults. Activity in the amygdala predicted enhanced emotional memory, with subsequent-memory activity greater for negative stimuli than for neutral stimuli, across age groups, a finding consistent with an overall enhancement of emotional memory. However, older adults recruited greater activity in anterior regions and less activity in posterior regions in general for negative stimuli that were subsequently remembered. Functional connectivity of the amygdala with the rest of the brain was consistent with age-related reductions in memory for negative stimuli: Older adults showed decreased functional connectivity between the amygdala and the hippocampus, but increased functional connectivity between the amygdala and dorsolateral prefrontal cortices. These findings suggest that age-related differences in the enhancement of emotional memory might reflect decreased connectivity between the amygdala and typical subsequent-memory regions, as well as the engagement of regulatory processes that inhibit emotional responses. 相似文献

Interference with activity of numerous cerebral structures produces memory deficiencies; in many instances, however, when animals are over-trained such interference becomes innocuous. Systemic administration of protein synthesis inhibitors impairs long-term retention; this effect has been interpreted to mean that protein synthesis is required for memory consolidation, though little is known about the effect of protein synthesis inhibitors on memory of enhanced learning in the rat. To further analyze the protective effect of enhanced learning against amnesic treatments, groups of Wistar rats were trained in a one-trial step-through inhibitory avoidance task, using different intensities of foot-shock during training. Cycloheximide (CXM; 2.8 mg/kg), an inhibitor of protein synthesis, was injected either 30 min before training or immediately after training. Twenty-four hours after training retention latencies were recorded. Our data showed that both pre- and post-training administration of CXM produced amnesia in those groups that had been trained with relatively low foot-shock intensities, but no impairment in retention was observed when relatively high intensities of foot-shock were administered. These and similar results lead us to conclude that protein synthesis inhibitors may interfere with memory consolidation, but their effect disappears when animals are submitted to an enhanced learning experience, calling into question the idea that protein synthesis is required for memory consolidation. 相似文献

The present study was aimed at assessing whether focusing attention on a task-relevant part of a word prevents processing
of its meaning. Participants performed a color-naming task on a prime word followed by lexical decision on a probe. Primes
were words, which could contain an embedded color word (e.g., “redemption”) written in an incongruent color. Probes were either semantically related (e.g., “confession”) or unrelated (e.g.,
“production”) to the prime word. A Stroop effect emerged for color words appearing either in the initial or in the final position
of the carrier word. A priming effect also emerged, with faster responses to probes semantically related to the prime. These
results are evidence that focusing attention on part of a prime (i.e., the embedded color word) does not prevent the semantic
processing of the entire word. 相似文献

The bilateral intranigral infusion of 1 micromol 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in adult male Wistar rats caused a specific and partial loss of substantia nigra pars compacta (SNc) dopamine neurons, a partial depletion of striatal dopamine, and a deficit to learn the intra-maze cued version of the Morris water maze. Pre-training the SNc rats in the spatial version of the water maze or simply maintaining the animals on the water maze platform reversed this deficit. This improvement was even observed when the order of the extra-maze cues presented to the rats during pre-training of the spatial version was changed during training of the intra-maze cued version. However, this deficit was not reversed either by maintaining the animals on the platform if the spatial cues were surrounded and covered with a curtain or by swimming sessions in the maze without the escape platform and the curtain. These findings suggest that none of the following elements alone, learned during the spatial task pre-training, could help SNc rats learn the intra-maze cued task: improvement of swimming skills or knowledge of the existence of the escape platform; distance between the platform and the border of the pool; location of a particular extra-maze cue; relations among extra-maze cues. However, the simultaneous presence of the escape platform and extra-maze cues (irrespective of their relational configuration) during the pre-training sessions proved to be necessary for this improving effect to occur. 相似文献
